This graphic depicts the passage of asteroid 2014 EC past Earth on March 6, 2014. The asteroid's closest approach is a distance equivalent to about one-sixth of the distance between Earth and the moon. Times indicated on the graphic are Universal Time. A time near closest approach, 2200 Universal Time, is 2 p.m. PST (5 p.m. EST).

NASA detects, tracks and characterizes asteroids and comets using both ground- and space-based telescopes. The Near-Earth Object Observations Program, commonly called "Spaceguard," discovers these objects, characterizes a subset of them and identifies their close approaches to determine if any could be potentially hazardous to our planet.
